If multiple buttons are pressed at the same time, the software interprets this as
a “no button pressed” condition. The only exception to this rule is if multiple
buttons are pressed and one of them is the OFF button. If the OFF button is
pressed in combination with any combination of other buttons, the processor
will behave as if the OFF button were pressed by itself.
